Pluggable Content Management Solution?

System

Greetings, I'm new to Content Managment and Interwoven and I have a couple of questions. I am currently in the process of refreshing a client's J2EE-based website. My client is considering using Content Management, but this decision will not be finalized until well into our re-design.

My main question is whether anyone has experience with creating a J2EE application that allows Interwoven to be "plugged in" at a later time? From the reading I've done so far, it appears that sites that leverage Interwoven are generally designed from the ground up around Interwoven Teamite.

Are we shooting ourselves in the foot by creating a J2EE solution and then trying to add Interwoven Teamsite at a later time or is it possible to craft a solution that will allow us to fully utilize Interwoven Teamsite at a later time?

Thanks for any help you can provide that will help me get a handle on this!
